I just had to reply: That's absolutley amazing! Fantastic job!
I play with the thought to switch from my Cooler Master Elite 110 to the DAN A4 SFX and was looking around to see what I have to expect when building in a case that's even smaller than the Elite 110. Then I stumbled across this thread and I'm glad I did. That little 40mm fan is probably one of the best solutions I'v ever seen.
Again, well done and thank you very much for sharing this here.
